—Nowadays excavations are mostly performed with
bentonite clay cycling which is so inappropriate in economical
and timing issues of projects.In this method introduced, all
unwanted machinery and constructions are limited and
replaced by a simple tube and nozzle designed for shotcreting
and restraining the drilled walls, which provides its stability
against falling down and also waterproofing bore walls against
water streaks, drilled through.In this experimental work, a new
device is designed and some tests were accomplished in soils
with different properties and all advantages and disadvantages
of this brand new method are informed.
